Protect additional areas with the Pawz Away Extra Mini Barrier Transmitter. You will be able to teach your pets to avoid areas inside your home and outside in the yard. The transmitter sends out a radio signal adjustable up to five feet and your pet wears a Receiver Collar with contacts that touch his neck. When your pet enters the forbidden area, he'll hear a series of beeps from the collar and he will feel a safe, static correction which is designed to startle and not punish. The Mini Pet Barrier will keep your pet off kitchen counters, away from the trash, and off your furniture to protect your pet and your home.
